' SPECIFIGATION forming part of Letters Patent No. 703,389, dated July 1, 1902.

Application filed April 17, 1901. Serial No. 56,269. (No model.)

To (LU w/wm it may concern.-

Be it known that I, GEORGE I-IowLErr DAVIS, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, haveinvented a certain new and useful Machine for Forming Stencils from whichMusic-Sheets are Printed, of which the followingis a specification.

My present invention relatesto animproved nlachine for forming stencils from which music-sheets are printed, and has for its object to provide avery simple device of this character which willbe very easy to operate and one wherein the stencil beingoperated upon may be readily manipulated.

In self-playing musical instruments oper-.

ated either pneumatically or electrically through the medium of a perforated notesheet it has become customary'to provide such note-sheets with suitable characters or marks to designate the various expressions in tone and speed to be given the composition during its performance; and it is the purpose of the present invention to provide a machine for forming the sheet-stencils from which to print or mark the said expression plete machine constructed in accordance with my invention. Fig. 2 is a detail side view, partly in section, of a portion of the machine.

Referring to the drawings, the referencenumeral 1 designates the base of the machine, which may be made in any desired form and which is provided upon each side with two bearings 2 and 3, one pair of which is in rear of the other. Within the two front bearings 2 is journaled a receiving-roller 4:, having fixed to one end thereof alarge milled head 5, for a purpose presently to appear.

of the delivery-roll, as will be seen.

Within the two rear bearings 3 is journaled a delivery-roller 6,the shaft f which is provided upon one end with a pinion 8, which meshes with a gear-wheel, said gearwheel being mounted upon a short shaft 10, journaled inclose proximity to the shaft 7 The gear-wheel 9 is provided with a crank-handle 12 or some other means whereby the same may be readily operated to communicate motion to the delivery-roll 6.

Secured to opposite sides of the frame 13 intermediate the receiving and delivery-rolls and somewhat above them is a metal bar 14,

v to which is attached a metal plate 15, having side pieces 16, and upon this plate between the side pieces is supported a wooden cutting block or' platen 17, preferably arranged on an incline, overwhich the stencil to be cut passesin its movement to and from the delivery and receiving rolls.

To the under side of the metalplate 15 are attached the inwardly-bent ends of a yokebar 18, which latter is located above the wooden cu ttingblock or platen 17 and lies parallel therewith, as shown. Tapped through this yoke-bar 18 is a series of clamping-screws 15), which are arranged to firmly hold the metalpattern stencil-plate 20 upon the stencil -sheet 21 and upon the wooden cutting block or platen 17.

In order that the operator may have his tools in close reach, I have provided a tool support or holder, which consists of a bar 22, located slightly above and in rear of the yoke-bar and which has its ends 23 bent downward and secured to opposite sides of the metal ba'se-frame. 'Ihisbar 22 is provided with a series of notches or recesses 23 to receive and retain the tools used by the workman.

It is desirable that the stencil-strip 21 be held taut during operation, and for this purpose I haveprovided afriction piece orspring 24', which is attached at one end to the shaft of the rollerator in anyother suitable manner and hasits'opposite end free andjacting by friction orpressure upon the end of the receiving-roller at. The degree'of pressure given this friction-spring is regulated by a thumbscrew 25, tapped through the frame of the machine, as shown in Fig. 1.

The operation of the machine maybe briefly stated, as follows: The stencil-sheet to be marked or cut is first rolled upon the delivery-roll 6, which roll is preferably removably mounted, and its end is ,then passed upward over the cutting block or platen 1'7 and from thence passed downward and secured to the receiving-roll 4, which latter is provided with any suitable means by which the said end of the stencil-sheet may be secured thereto. This stencil-sheet has marked thereon in any suitable manner and at the proper points the particular expression-marks to be out therein, and as these marks appear over the cutting block or platen during the movement of the sheet, which is accomplished by turning the milled wheel 5, the operator places his metal pattern-plate 20, bearing the appropriate mark,upon said sheet, as shown, and then clamps the same firmly in position by means oftheclamping-screws19. Theoperatornow takes his tools, which consist of sharp cutting instruments, and removes or cuts the material from the sheet, so as to leave openings therein to represent the particular expression-mark, such as retard, tempo, and the like, as illustrated in the drawings. The stencil-sheet is also cut with a deviating or zigzagline of perforations, (represented by the numerals 26.) WVhen the sheet or stencil has been cut at all the points indicated, it is rewound upon the delivery-roll by simplyrotating the gear-wheel 9 by means of the handle 12. The stencil is now complete and may be removed and passed through a printing-press in contact with the inking-roller, the ink passing through the apertures in the sheet and upon a music-sheet to be marked.

What I claim is- 1. In a machine for forming sheet-stencils, the combination with a suitable base-frame, of a delivery-roll and a receiving-roll journaled in said frame, a cutting block or platen arranged above the said rolls and over which the sheet-stencil is moved during its passage from one roll to the other and means for clamping a stencil-plate upon said block or platen.

2.
